Thank you so much, really helpful example.
I am having trouble creating the anotation MongoElement :
"MongoElement annotation;
if ((annotation = readMethod.getAnnotation(MongoElement.class)) != null) { keySet.add(desc.getName());
}"
Eclipse complains:"MongoElement cannot be resolved to a type" and
"Bound mismatch: The generic method getAnnotation(Class) of type AnnotatedElement is not applicable for the arguments (Class). The inferred type MongoElement is not a valid substitute for the bounded parameter " any ideas? thank you in advanced

Nice article, i think NoSQL solutions are future.

Here is one more way to convert your project to MongoDB with JPA.

So I have been reading about hibernate-memcahced, spymemcached, etc. All of these solutions to make Hibernate work with memcached. The catch is you need to defined all of your queries and entities as cacheable, and yada yada yada. In your opinion isnt there a simpler way? Cant we ditch hibernate all together and use a different ORM framework that lends itself better to memcached? The php memcached examples are simple. Cant we expand upon that simplicity in java?

2010-06-16T13:02:36.283-07:00

The above example miss some method implementations (at least not for mongo v2 java driver). So here is a full class:

public class DbObjectAdapter implements DBObject {
private static final Logger log = LoggerFactory.getLogger(DbObjectAdapter.class);
private final BeanUtilsBean beanUtils;
private final Object entity;
private final Set keySet;
private boolean partialObject;

public DbObjectAdapter(Object entity) {
if (entity == null) {
throw new IllegalArgumentException("Entity must not be null");
}
if (!entity.getClass().isAnnotationPresent(Entity.class)) {
throw new IllegalArgumentException("Entity class must have annotation javax.persistence.Entity present");
}
this.entity = entity;
this.beanUtils = new BeanUtilsBean();
this.keySet = new HashSet();
initKeySet();
}

@Override
public Object put(String name, Object value) {
try {
beanUtils.setProperty(entity, name, value);
} catch (Exception e) {
log.error("Failed setting property", e);
}
return value;
}

@Override
public void putAll(BSONObject bsonObject) {
putAll(bsonObject.toMap());
}

@Override
public void putAll(Map map) {
try {
beanUtils.populate(entity, map);
} catch (Exception e) {
log.error("Failed populating map", e);
}
}

@Override
public Object get(String name) {
try {
return beanUtils.getProperty(entity, name);
} catch (Exception e) {
return null;
}
}

@Override
public Map toMap() {
Map map = Maps.newHashMap();
Iterator iterator = keySet.iterator();
while (iterator.hasNext()) {
String key = iterator.next();
map.put(key, get(key));
}

return map;
}

@Override
public Object removeField(String s) {
Object retVal = get(s);
keySet.remove(s);
return retVal;
}

@Override
public boolean containsKey(String s) {
return keySet.contains(s);
}

@Override
public boolean containsField(String s) {
return keySet.contains(s);
}

@Override
public Set keySet() {
return keySet;
}

private void initKeySet() {
final PropertyDescriptor[] descriptors = beanUtils.getPropertyUtils().getPropertyDescriptors(entity);
for (PropertyDescriptor desc : descriptors) {
final Method readMethod = desc.getReadMethod();
MongoElement annotation;
if ((annotation = readMethod.getAnnotation(MongoElement.class)) != null) {
keySet.add(desc.getName());
}
}
}

@Override
public void markAsPartialObject() {
partialObject = true;
}

@Override
public boolean isPartialObject() {
return partialObject;
}
}

We ran into this with the Terracotta Hibernate cache provider (which is distributed) too. In the first rev of the Terracotta product we used bytecode manipulation to rewrite the concurrency strategies for greater concurrency. In the new "Darwin" version, Terracotta is providing custom cache concurrency strategy classes for use with 3.2.x (since it's a pluggable part of Hibernate) as well as a 3.3.x cache provider that can take care of it in the provider.
